Added, Draw Grid mode: "Lock slices to grid" now operates in 4 modes: "None", "Horizontal", "Vertical" and "Both". Can be helpful when drawing ladders and such.

Changed, all drawing modes: changeable drawing mode settings are now persistent.
Changed: "Dynamic grid size" mode is now disabled when changing grid size manually.
Documentation: "Command Line Parameters" topic contained a lot of incorrect information...
Updated ZDoom_DECORATE.cfg.

 ==========================================================================================
 
 Parameters:
 
-- wadfile
+wadfile
 This is a .WAD file to load immediately after Doom Builder has started up. Unless -map
 and -cfg are used, this will show the map-options dialog.
 
-- map
-Where 'mapname' is the name of the map (map header lump name) such as MAP01 or E1M1. When
+-map "mapname"
+Where "mapname" is the name of the map (map header lump name) such as MAP01 or E1M1. When
 specified, this will indicate the map to load from the specified wad file. Use in
 combination with -cfg to provide the required information to skip the map-options dialog.
 
-- cfg
-Where 'configname' is a game configuration filename, for example, "ZDoom_DoomHexen.cfg".
+-cfg "configname"
+-config "configname"
+Where "configname" is a game configuration filename, for example, "ZDoom_DoomHexen.cfg".
 Do NOT include the path, all game configurations must be in the Configurations subfolder.
 When used in combination with -map this will provide the required information to load a
 map directly and skip the map-options dialog.
 
-- delaywindow
+-delaywindow
 This delays showing the main interface window until the automatic map loading from
 command line parameters is completed, and the program is not terminating yet. This is
 usefull for plugins that can be used to perform batch processes where the showing of the
 main interface window is not desired. If a plugin completes it's actions on map load and
 terminates the application immediately, the main window will not be shown at all.
 
-- nosettings
+-nosettings
 When this parameter is specified, Doom Builder will not load your preferences or game
 configuration settings and will use the default settings instead. You will not lose your
 original settings, but when this parameter is specified your settings will not be saved.
 
-- strictpatches
+-strictpatches
 Specify this parameter to enforce strictly loading texture patches from between P_START
 and P_END marker lumps only. This can solve lump name conflicts, but old WAD files do not
 always adhere to this rule.
 
-- resource
+-portable
+The editor will be launched in portable mode. It will use the "GZBuilder.cfg" located in 
+the program directory instead of the one located in the 
+"%LocalAppData%\Doom Builder\GZBuilder.cfg" to load and save program settings. Log and 
+crash report files will be also created in the program directory.
+
+-resource <resource type> [flags] "path\to\resource"
 When -wadfile is specified, the -resource option can be used to add additional resources
 that must be loaded along with the wad file. Note that these are added to the resources
 which are automatically loaded due to the selection of a game configuration. You can
 repeat this option for any number of resources you wish to add. As always, the last
-specified resource will override any data in earlier specified resource. This parameter
-has the following arguments:
